Szabolcs Nagy c9783e4d32 treat STB_WEAK and STB_GNU_UNIQUE like STB_GLOBAL in find_sym ... A weak symbol definition is not special during dynamic linking, so don't let a strong definition in a later module override it. (glibc dynamic linker allows overriding weak definitions if LD_DYNAMIC_WEAK is set, musl does not.) STB_GNU_UNIQUE means that the symbol is global, even if it is in a module that's loaded with RTLD_LOCAL, and all references resolve to the same definition. This semantics is only relevant for c++ plugin systems and even there it's often not what the user wants (so it can be turned off in g++ by -fno-gnu-unique when the c++ shared lib is compiled). In musl just treat it like STB_GLOBAL.		2017-03-11 19:10:57 -05:00
